To (ti/Z wit-0712, it ntrty concern:

Be it known that I, MOCLELLAND MYnRs, a citizen of the United States of America, residing at Moosic, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Glass- Molding Apparatus, of which the following is a specification.

This invention relates to glass-molding machinery, and particularly to a machine designed for use in molding caps for jars, insulators, and other articles which are threaded either internally or externally, the device as here disclosed, however, being confined to a means for threading the article internally.

An object of this invention is to produce means whereby a series of molds are automatically brought into alinement with a presser-head and extracting-plunger succes sively, whereby the material is pressed into shape and finally extracted from the mold.

The invention further consists inthe provision of novel means whereby the cap, insulator, or other-article is pressed from the outside and whereby it is manufactured in its upright position or with the outer surface up.

Furthermore, an object of this invention is to provide novel means for rotating the threading device, whereby as the mold is carried around the table the threading device is.

view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts throughout the several views, in which Figure 1 is a view in elevation, partly in section, illustrating a machine embodying the invention. Fig. 2 is a horizontal sectional view taken on a line corresponding with the line {are of Fig. 1. Fig. 3 is a horizontal sectional view taken on a line corresponding l one on each side of the said truck.

with the line 1 ;1 of Fig. 1. Fig. 4 is a detail view showing the controlling-lever and its connections- Fig. 5 is a sectional view showing the automatically-operatcd detent. Fig. 6 is a plan view of the threader-actuating means. Fig. 7 is a plan view showing the parts in a different position from that shown in Fig. 6. Figs. 8 and 9 are de ail views showing the construction'of the molds.

In the drawings, A indicates a suitable truck provided with a standard or column B at each end,which column supports the beam Q. Mounted on the beam C is a cylinder D. \Vithin the cylinder D isa piston E, havinga depending piston-rod F, which passes through an aperture in the beam and terminates in a threaded portion Gr. A plate H is secured on the end of the piston through the medium of the nuts I, whereby the position of the plate may be changed with relation to the end of the piston. Bolts J are slidable in the plate and are encircled by springs K. A presserhead L is attached to the end of the piston-rod and is adapted to move through the opening in a plate M, which is secured on the lower ends of the bolts J-that is, as the piston is projected and the plate M is arrested, as hereinafter described, the presser-head will move with relation to the plate M and pass through the opening in the plate and press the material in the mold.

The piston is moved preferably by compressed air, which is delivered to opposite sides of said piston through the medium of pipes N and O. The pipe N leads to and communicates with the rear end of a cylinder P and the pipe 0 leads to and communicates with a valve Q, with which the pipe N is also connected through the medium of the short pipe R. A pipe S is tapped and the pipe 0 extends to the end of the cylinder P opposite to end to which the pipe N is tapped, while another pipe T is tapped into the valve Q and leads to any suitable source of supply. It is preferable tohave the pipe connections so arranged as to insure a depression of the piston in the cylinder 1) and at the same time the piston in the cylinder P to project the piston-rod, while the pipes S and O are so connected as to be open to move the cylinder in the piston up and at the same time to move the piston in the cylinder P to retract the piston-rod thereof for purposes to be prescntly explained.

Mounted on the truck A are two posts a a, A table 6 is supported by and attached to said posts and to the brackets 0, extending from the column B. This table is provided with a ballway (Z for the purpose of receiving antifriction-balls, on which the rotatable table 5 is mounted in order to reduce friction. The stationary table is provided with a camminggroove 2, which is curved inwardly, as at 3, and has a straight portion 11 diametrically op posite that portion which is inwardly curved. The stationary table has a peripheral lug A with a curved edge, which forms acam. The stationary table has an extension B, provided with a groove 4, the outer edge of which is bounded by a flange 5, having its inner surface or edge parallel with the edge of the table and the lug A thereof.

A shaft? is journaled centrally of the table and extends therethrough and is keyed or otherwise secured to the rotatable table 0, and the said shaft is rotated through a mechanism to be presently explained. Suffice it to say that the said table is rotated and the plates 8 are pivoted thereto by the studs or pins 9 in a manner to allow the free oscillation of the said plates with relation to the rotatable table. Studs 10 are secured to the under surface of the plates 8 and depend through the. slots D of the rotatable table and into the groove 2 of the stationary table. The studs 10 are provided with antifriction-rollers E, which rotate in the groove of the stationary table as they are carried therein with the rotation of the rotatable table. It will be observed that as the studs 10 move in the groove 2 the camming action of the curved portion of the slot acts to turn the plates on their axes, thereby partially rotating the said plates with each rotation of the table. At a point diametrically opposite said studs 10 are depending studs F, which are designed toride in the slots 4: to engage the flange 5 and the cam edge of the lug A heretofore described. The segmental portions of the plates 8 are provided with teeth G, and the said teeth mesh with the pinions H, rotatable on the table.

It will be observed in operation when the table is moved in the direction of the arrow as in Fig. 2 the plates 8 on the table will be moved in the direction of the arrow 3/ indicated on said plates. When the parts are brought to the position shown in Fig. 2, the direction of rotation of the plates is reversed, owing to the studs 10 having moved in a circular direction through the curved portion 3 of the groove 2.

In the enlarged detail views shown in Figs. 6 and 7 a fragment of a rotatable table is shown with one end of the plates 8 illustrated. The pinions H each have splined thereto a sleeve member f, having its upper end reduced and provided with a male thread 9, and the said sleeve member is internally threaded on a bolt it, so that with the rotation of the the bolt is reduced, and the reduced portion projects through the sleeve member and terminates in a head 2', which is normally seated in a recess in the upper end of the sleeve and has its upper surface flush with the upper surface of the sleeve. The mold is formed in two sections pivoted together at the point 20, and each member has a lug 21, to which a handle is attached for the purpose of manipulation.

In the operation of the device the mold is placed under the plunger, and glass from which the article is to be formed is dropped into the top of the mold and the plunger is brought down in the ordinary manner. The rotation of the sleeve on the bolt results in the said sleeve traveling down the bolt and the threaded section of the sleeve is withdrawn from the article being formed. The said article is held in position by the head of the bolt while the said sleeve is being withdrawn, and after the threads of the sleeve are disengaged from the threads of the article the said article is supported on the head of the bolt and is removed in the ordinary manner. With the reversal of the direction of rotation of the pinion as heretofore described in connection with the operation of the plate 8 the sleeve is moved upward until the head rests in the recess in the end of the sleeve or to the normal position, which is shown in Figs. 1 and 8.

The foregoing description with relation to the mold described one of a series of molds, as illustrated in Fig. 1, and it will be apparent that the molds are successively brought into alinement with the plunger or presser and also that they are successively discharged after the molds move away from the presser.

The means for rotating the table comprise a ratchet-wheel j, which is mounted on the shaft 7, and coacting with the said ratchetwheel is a dog it. An arm Z carries the dog in and has a slot on in its end to receive the point 72, which is on the piston-rod 0. The piston-rod operates through the guide 19, which is suitably supported on the table. As the actuating agent, either air or steam, is admitted to alternate ends of the piston P, its piston-rod is reciprocated, and hence the arm Z is oscillated. This oscillation of the arm intermittently rotates the ratchet-wheel, and hence motion is communicated to the table.

For the purpose of retaining the mold in perfect alinement with the presser I provide a series of apertures q in the movable table, which are adapted to aline with a hole in the stationary table, and the bolt (6 is adapted to enter the holes of the movable table successively for the purpose of retaining the said movable table stationary while the plunger is operated to press the glass. It is my purpose to operate the bolt and with the operation of the bolt to control the valve Q for sleeve it is reciprocated. The upper end of 1 supplying air to the two cylinders D and P simultaneously --th'at is, when the bolt is seated With one of the molds under the presser air is admitted to the top of the cylinder D and to the outer end of the cylinder P. This pressure results in driving the presser in contact with the material in the mold, and at the same time projects the piston of the cylinder P so that the dog carried by the arm Z engages teeth in advance of the teeth it engaged before it was projected. As the material has been pressed sufiiciently, the bolt is withdrawn from the hole in the movable table, so as to release the said table, and at the same time the valve Q is moved to admitair to the bottom of the cylinder P, thus elevating the presser and retracting the piston of the cylinder P, which results in turning the table through the agency of the arm, dog, and ratchet.

The mechanism for retaining the stationary table during the operation of the plunger comprises, as stated, a bolt (6, which is adapted to pass through the coinciding apertures of the stationary table and movable table, and when said bolt is depressed means are provided for retaining it depressed until the table has traveled a predetermined distance, when the latch is tripped and the bolt released. The bolt to is carried on a lever I), which lever is pivoted on the pin a and supported by the hanger 0 The lever terminates in a handle cl, whichis depressed by the operator when the bolt is drawn from the aperture of the movable table. The bolt is sufliciently depressed to cause the recess a to aline with the latch-bolt a which is spring-pressed to hold it normally projected. The latch-bolt has a lever (0*, which is pivoted at the point a and said lever has a plain surface a,

which is engaged by the lugs a contacting with the lever (f. The latch-bolt a is retracted and the bolt to is released, and when it is released the action of the spring a which is connected to the end lever, tends to carry the bolt upward to seat itin the manner heretofore described. The lever b has an arm (Z which moves with it, and said arm has on its lower end a link a, which is connected to the stem of the valve Q, so that the said valve is rotated for the purpose of establishing communication with the pipes to carry the actuating agents to and from the cylinders D and 1, as heretofore fully explained.
